Breast imaging is a subspecialty within diagnostic radiology devoted to the diagnosis and treatment of breast diseases. Whether with magnetic resonance imaging or with nuclear medicine or with mammograms and scans using other imaging modalities, breast imaging is a vital medical diagnostic protocol. Oakstone Publishing, LLC is your authoritative source for clinical breast imaging courses and breast imaging CME (continuing medical education).
Time inevitably brings change. More than six and a half years after Radiology Daily began, this is the final post. Don’t worry! Launching next month will be a free, time-saving monthly e-newsletter, Oakstone’s new Highlights in Radiology. Here’s a taste of what you’ll get:
Insights from respected colleagues in the field of radiology and diagnostic imaging
Physician reviews of—and commentary on—radiology-related articles from … read more »
A health-insurance company’s “price transparency program” succeeded in driving insured patients to less-expensive MRI facilities and away from hospital-based facilities, according to an article in the current edition of Health Affairs.
The insurer was WellPoint. One of its subsidiaries commissioned the study, and another conducted it. The study looked at more than 100,000 members of WellPoint health plans from 2010 through 2012. … read more »
The surprisingly rapid spread of digital breast tomosynthesis, also known as 3-D mammography, may be an unintended—but beneficial—consequence of hospital consolidation.
Digital breast tomosynthesis (DBT) is costly, partly because one manufacturer, Hologic, has the U.S. market to itself (although it will likely soon have competition from GE and Siemens, which sell 3-D mammography systems in Europe). A large, consolidated health care … read more »
A new technology that can create an “acoustic bottle” in midair could improve ultrasound imaging, according to researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory in Berkeley, California. The technique also shows promise in a number of more exotic fields, including acoustic cloaking, particle manipulation, and levitation.

The discovery by University of Wisconsin researchers of genes that are necessary for surviving high levels of radiation has potentially big implications for imaging and radiation therapy.
The researchers developed a highly radiation–resistant strain of Escherichia coli by exposing cultures of the bacterium to extreme doses of radiation. “We blasted the cultures until 99 percent of the bacteria were dead,” said Michael M. … read more »
A new type of nanoparticle actively seeks out cancer cells, then automatically assembles itself into clumps large enough to clearly show up on MRI scans.
Researchers at Imperial College London created the nanoparticle to increase both the sensitivity and specificity of MRI in detecting small, early-stage tumors. Nicholas J. Long, PhD, the Sir Edward Frankland BP Chair of Inorganic Chemistry, explained … read more »
New technologies, such as digital mammography and computer-aided detection, are being used for breast cancer screening of Medicare patients. They’re costing more, but they’re not finding cancers earlier.
That’s the conclusion of a new study led by Yale School of Medicine researchers, using data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) Program. The researchers determined that mammography … read more »
What if chemotherapy drugs could be squirted directly onto breast tumors from tiny reservoirs inside the body in short bursts, on demand?
They can, thanks to a self-healing gel that amounts to a miniature drug vial that can be opened and closed via ultrasound.
David J. Mooney, PhD, a core faculty member at Harvard University’s Wyss Institute for Biologically Inspired Engineering, led … read more »
State regulation of radiologic technologists has “little impact on public health and safety” and should be abolished, according to a staff report of an agency of the Texas Legislature.
Christine Lung, vice president of government relations and public policy for the American Society of Radiologic Technologists, begs to differ:
Everyone knows that radiation is a carcinogen. If performed incorrectly, it’s a direct … read more »
Emily F. Conant, MD, didn’t mince words about the implications of the latest blockbuster mammography study:
It’s the most exciting improvement to mammography that I have seen in my career, even more important for women than the conversion from film-screen mammography to digital mammography. 3-D mammography finds more clinically significant breast cancers earlier, which is the key so that women have … read more »
